Problem with pattern matching

Need in -if- statement that will detect when a 2 char string contains a non digit.( I’ve already checked the string's lenght so it's guaranteed to be 2 chars long.) In other words. The string can contain "00","01"."02"…"99" but NOT stuff like " 0". "0 ", "9A", "Z7"...

if ($my_dat =~ /^[0-9]/ ) {some code here;}

Works if the 1st char is not a digit ( catches stuff like " 0" and "A4" ) but misses stuff if 2nd char is not a digit ( Misses stuff like "0 " and "7W")

Can someone help ?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:

  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
